Correct Answer - Option 2 : 384

Given:

The volume of a cube is 512 cm3

Formula Used:

Volume of cube = Side3

Total surface area = 6 × Side2

Calculation:

The volume of a cube is 512 cm3.

Let the side be x.

⇒ x3 = 512

⇒ x = 8 cm

Total surface area = 6 × 82 = 384 cm2

∴ The total surface area is 384 cm2.
